no force act on it
Static friction is the force that acts on an object that is not moving. Other kinds of friction include fluid friction and rolling friction.
2 forces act on a body when it is ... Weight&buoyant force
When several forces act on a body and the result of the force is zero it is considered to be balanced force.
The normal force acts perpendicular to a body and in the downward direction.
no force act on it
for every force which act on one body action force there is an equal and opposite forces reaction force which act on same other body
Static friction is the force that acts on an object that is not moving. Other kinds of friction include fluid friction and rolling friction.
The force acting on an object "A" from outside is action force , and the reaction force is the force exerted by A to the outside object . Therefore, it is obvious that action force and the corresponding reaction force cannot act on one and the same body.
Centripetal force makes a satellite orbit a body.
2 forces act on a body when it is ... Weight&buoyant force
When several forces act on a body and the result of the force is zero it is considered to be balanced force.
Gravity, pressure.
In the direction opposite to that of the sliding body.
The normal force acts perpendicular to a body and in the downward direction.
The patella is a pulley
there is nothing called as principle of friction. friction is just a force which will act in the opposite direction of which you apply force.
